I play it straight up. If it is for goods and services then that is what I click. If it is money for a friend or buddy then that is what I check.

When I sell parts on here I expect people to click goods and services. Some people who I know or I've sold parts to in the past send the money as friend. I'm fine with that but I'd never tell someone to do that. If I'm selling products then I expect to pay the man his toll.
